使用Ffmpeg获取视频基本信息

如果还未安装ffmpeg, 首先需要安装ffmpeg,不同平台有不同的安装方式，可以参考 https://upwqy.com/details/422.html 

1、 使用命令行

$file = '';// 视频地址
ob_start();
$ffmpegCmd = 'ffmpeg -i "%s" 2>&1';

passthru(sprintf($ffmpegCmd, $file));

$videoInfo = ob_get_contents();
ob_end_clean();

// 使用输出缓冲，获取ffmpeg所有输出内容
$ret = [];
    // Duration: 00:33:42.64, start: 0.000000, bitrate: 152 kb/s
if (preg_match('/Duration: (.*?), start: (.*?), bitrate: (\\d*) kb\\/s/', $videoInfo, $matches)) {
$ret['duration'] = explode('.', $matches[1])[0]; // 视频长度
$duration = explode(':', $matches[1]);
$ret['seconds'] = $duration[0] * 3600 + $duration[1] * 60 + $duration[2]; // 转为秒数
$ret['start'] = $matches[2]; // 开始时间
}
if (isset($ret['seconds'], $ret['start'])) {
    $ret['play_time'] = $ret['seconds'] + $ret['start']; // 实际播放时间
}

$header_array = get_headers($file, true);
$ret['size'] = $header_array['Content-Length'];

通过执行以上代码将获取视频的时长、秒、大小。

视频地址可以是本地视频或者远程视频地址

array:5 [
  "duration" => "00:19:31"
  "seconds" => 1171.68
  "start" => "0.000000"
  "play_time" => 1171.68
  "size" => "193227373"
]

2、使用 php-ffmpeg/php-ffmpeg

首先引入php-ffmpeg依赖

composer require php-ffmpeg/php-ffmpeg

$url = 'input.mp4';// 替换为真实视频链接
//        $ffmpeg = \FFMpeg\FFMpeg::create([
//            'ffmpeg.binaries' => '/usr/bin/ffmpeg',
//            'ffprobe.binaries' => '/usr/bin/ffprobe',
//            'timeout' => 3600, // The timeout for the underlying process
//            'ffmpeg.threads' => 12,   // The number of threads that FFMpeg should use
//        ]);

$ffmpeg = \FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($url);
$data= [
    'width' => $video->getStreams()->videos()->first()->get('width'),
    'height' => $video->getStreams()->videos()->first()->get('height'),
    'duration' => $video->getStreams()->videos()->first()->get('duration'),
];
dump($data);

通过以上代码执行后输出视频的宽，高，时长

array:4 [
  "width" => 1920
  "height" => 1080
  "duration" => "1171.680000"
]

注意：如果ffmpeg没有配置系统环境变量，需要在create时指定ffmpeg的安装路径

另外通过打印 dump($video->getStreams()->videos()->first()); 可以查看视频的其他属性，然后通过 $video->getStreams()->videos()->first()->get('属性名') 的方式获取指定属性值
